FTD LDAPs cert subject ctx->error:

Hello everybody,

 

I configured remote vpn with ldaps authentification on the FTD device. If I try to connect with anyconnect, than I take the error:

 

PKI[8]: val status=1: cert subject: /CN=dc Root CA - 1. ctx->error: (0)ok, cert_idx: 2
PKI[8]: val status=1: cert subject: /DC=local/DC=dc/CN=dc Sub CA - 1. ctx->error: (0)ok, cert_idx: 1

PKI[8]: val status=1: cert subject: /DC=local/DC=dc/OU=Domain Controllers/CN=SRV. ctx->error: (0)ok, cert_idx: 0

Please tell me what could be the reason?

Hi Raul,

 

thank for your answer.

I did it. The FTD has a identity certificate from root ca. I installed root ca and root sub ca too.
